Hi. Maybe either go a chalk pink or duck egg on the walls to add some colour. Or alternatively add the colour in the curtains, accessories and bedding. I've attached this chair from alison at home which is on clearance at the moment (found it for another post and think it will suit your room!). Images are from argos and buckeye state. I think bunting can look really good in a girls room and a way to add colour. Or if you went with the 2nd option, maybe add some framed butterfly art on the walls. Having a couple of teddies or strategically placed wooden blocks can keep the room young and look really good. By the way the pinks in these pics are pretty pink but I'd go very pastel or chalk personally and just add splashes of it.

I found the Dulux Visualator, or whatever it’s called, to be pretty useless. I used it once to visualise my old sitting room colour just to see how accurate it was. My walls were Dulux Elderflower so compared it on the Dulux online thingy and it was completely different!

That’s good news, could be expensive otherwise! I was just a little worried a super king could be too big. I’d draw the room to scale on graph paper and do the same for the furniture you want but cut it out and try it around the room. Re shopping, the chair and rug were Oka ( a lot is out of stock atm but they do some really good cushions and lamps too.). The chest and bedside were by Feather and Black, the blank box also by sofa. Com. The lamp was by Loaf and the blind fabric was Susie Watson (also do accessories etc). Pooky also do a number of good lights and lamps. It may also be worth looking at Neptune. Cox and Cox are mainly scandi but I think you’d like some of their things.

How big are the two double bedrooms? Is there any chance of claiming a bit of space from each to create a small nursery for the baby? Assuming that's an outside wall, you could look at borrowing some light with fanlights etc?
